Random Notes

Can implement incrementally

One nice thing about busybox/toybox/toolbox is you can install multiple
implementations side by side, and have what symlinks you create (or what
comes first in the $PATH) determine who is implementing what.

This allows gradual transitions. Each release, we replace a couple more
commands from the old one, until the old one finally isn't being used for
anything anymore and we can uninstall it...
